An expert has concluded that Roy Moore inscribed a message in the yearbook of a woman who says he sexually assaulted her when she was 16, according to the accuser's lawyer.

Moore for weeks has denied that the 1977 message was his handwriting and said he doesn't remember the woman, Beverly Young Nelson. But in a news conference Friday in Atlanta, attorney Gloria Allred said handwriting expert Arthur T. Anthony compared the yearbook signature to others by Moore in the years since and determined he wrote the decades-old entry.

Below it is written a date, "12-22-1977," and "Olde Hickory House," the restaurant where Young worked. Moore supporters used discrepancies in the handwriting between those notes and the message to bring the entry into question, but Young said she wrote the notes herself to remember when and where a man she respected wrote the message.

Young said she has been subjected to threats and is living "behind triple-locked doors" since going public with her accusation last month.

"Since I spoke about my experience with Roy Moore when I was only 16 years old, I have been the target of threats and lies," she said. "A talk radio host said that I should be put in the town square and stoned and he said he wanted to be the first to throw the largest stone at me. Someone even sent me a photo of a casket, which I took as a threat."

Moore has frequently and loudly denied the accusations from Young and other women, and while his poll numbers bounced back from an initial hit, the stories are making Tuesday's election much closer than expected for the conservative Republican.
